Hi Paolo,
Here is the key element we should think about, and why I think this
specific warning is not useful. GCC supports only 2s complement
targets. Given that, I don't see what this "altering value"
diagnostoc is helping.
I consider that a conversion from T to U may alter value if a round
trip may give a different result back. E.g.
Given
U u = t;
the assertion
assert (T(u) == t);
may fail for some value in T.
